Water quality is one of the most important concerns. The heavy metals in drinking water may cause severe health problems in human beings and also effect the growth and metabolic activities of plants. In this study heavy metals evaluated along with Na and K in the ground water of Raisar and its surrounding villages in district Bikaner of Rajasthan state. For this study 20 ground water samples were collected in year 2012. Th ese samples were subjected to analysis for heavy metal like Fe, Mn, Cu and Zn by AAS method and Na and K by Flame Photometry method. The analysis of samples shows that following metals ranged from: Fe (0.02 to 0.1 ppm), Mn (0.005 to 0.079 ppm), Cu (0.02 to 0.25 ppm), Zn (1.8 tito 5.8 ppm), Na + (77 to 901 ppm) and K + (2 to 12 ppm). The results obtained were compared with BIS standards for drinking water and FAO standard for irrigation water. The presen ce of the heavy metals like Cu and Zn with Na + in ground water beyond the desirable limit warns for the disease in living beings. Our study suggested the preventive measures should be adopted to control the contamination of ground water of this region.
